Y 8 Claims.

This invention relates to new and useful im- Drovements in an electric water-heating system, and is a substitute for my earlier abandoned application Serial No. 109,220, filed November 5, 1936.

The invention has for an object the construction of a device as mentioned which is characterized by a container housing a water coil, and an electric heater within the container arranged to heat the coil.

More specifically, in one form of the invention it is contemplated to construct the water coil with an inlet which may be attached to a faucet.

A still further object of the invention is to arrange the water coil in another form of the invention with an inlet and an outlet which may be connected in series in a water supply, preferably near a faucet or outlet.

Another object of the invention is to construct the container of sections so as to be capable of being manually expanded or contracted and to arrange the water coil on one of these sections, and to arrange the electric heater on the other of these sections. With this arrangement it is {possible to change the radiating qualities, or the amount of heat supplied by the electri heater to the coil.

. A further object of the invention is to provide rheostats or other controls for the current to widen the degree to which the heat supply may becontrolled.

. Still another object of this invention proposes forming the coil of separate coiled sections with the provision of a separate electric heating element within each of the coiled sections in a manner to more efllciently heat the water within each section.

. It is a further object of the present invention to provide a single rheostat for controlling the operation of the electric heating element or to provide a rheostat for controlling the opera tion of each electric heating element independently of the other in a manner to permit the operation of each heating element to be independently controlled to meet desired requirements.

.Another object f the invention is the construction of a. device as mentioned which is simple and durable and which may be manufactured and sold at a reasonable cost.

1 For further comprehension of the invention,

and of the objects andadvantages thereof, reference will be had to the following description and accompanying drawings, and to the appended. claims in which the various novel features of '1 the invention are more particularly set forth.

The electric water-heating system, according to this invention, comprises a container I0 composed of sections Ill and III telescopically engaged with each other so that they may be manually moved to expand or contract the container, 2. water heater coil II is supported within the container on one of the sections and has an in-- let II and an outlet II. An electric heater I2 is supported within the container on the other of said sections.

The section I0 is the outer of the two and has.

its free edge I3 bent inwards and adapted to cooperate with the outbent edge I4 of the section I0 for limiting the expansion 0f the container. Several bosses I5 are arranged upon the side of the section I0 and support clamp screws I8 adapted to abut the section ID by which the container may be locked in fixed position.

The water coil II is arranged in two helical coil sections II and II. These sections are connected at their bottom ends by a coupling IT. The top end of the section I I" connects with the inlet I I. This inlet preferably has a rubber gasket I8 at its mouth by which it may be forced upon a faucet and maintain its position frictionally. The upper end of the section II of the water coil II connects with the discharge I l The electric heater I2 includes a pair of heating elements I2 and I2 which extend respec-- tively through the coil sections I I and I I This heater is mountedupon a base I9 attached to the container section ,III. A pair of terminals 20 project from the base I9 and are adapted to be engaged by a conventional electric plug, indicated by the dot and dash lines 2I. This plug is associated with a cable 22, also shown by dot includes a manually controllable rheostat 24 and the heating elements l2 and E2 of the electric heater l2, so that operation of the heater may be manually controlled by adjusting the single rheostat 24.

The device may be easily engaged upon a faucet, and upon switching on ofthe electricity,

hot water "may generated andsupplied {in -a--' very short period of time. The temperature of this water may be controlled by adjusting the rheostat 24 to control the amount of current pass ing through the electric heat'r i2;- la-runner control of the temperature of the water'is possible by adjusting the position of the'cas'irig se'c tion Ni This casing section rnay be lotvereii;

so as to partially remove thehatriz' marine proximity of the Water coil ll. Furthermore,

the surface of the container may thus be increased.
